Overview¶

An aroma cup is a small, standardised vessel used in professional coffee tasting and sensory evaluation to assess the aromatic character of brewed coffee in isolation from its other sensory properties. Used as part of cupping protocols and sensory training, aroma cups allow tasters to focus on volatile aroma compounds before tasting — a technique drawn from wine and spirits evaluation practice. The term is also used more broadly to describe any cup designed or marketed specifically for the evaluation or appreciation of coffee aroma, including lidded cups that trap volatile aromatics.

Role of Aroma in Coffee Evaluation¶

Aroma is the primary sensory pathway for flavour perception in coffee. The vast majority of what is experienced as "flavour" in the cup is in fact olfactory — detected via retronasal olfaction (aromas travelling up from the mouth to the olfactory receptors) rather than by taste receptors on the tongue. Taste receptors detect only the basic tastes: sweet, sour, salty, bitter, and umami.

Coffee contains over 1,000 volatile aroma compounds identified to date. The SCA Flavour Wheel organises coffee aromatics into hierarchical categories — fruity, floral, sweet, nutty/cocoa, spicy, roasted, and green/vegetative — derived from the World Coffee Research Sensory Lexicon. See SCA Flavour Wheel.

Use in Cupping¶

In the SCA cupping protocol, aroma is formally evaluated at two stages:

Dry fragrance — the aroma of freshly ground dry coffee before water is added; evaluated by sniffing the grounds in the cupping bowl
Wet aroma — the aroma of brewed coffee immediately after hot water is added and the crust broken; evaluated by sniffing close to the surface of the bowl

Dedicated aroma cups are sometimes used in training contexts to present reference aromas for calibration — tasters smell a known reference (from a standards kit such as Le Nez du Café or Specialty Coffee Association aroma reference sets) before evaluating actual coffees, anchoring their sensory vocabulary. See Cupping.

Aroma Reference Kits¶

A widely used professional tool for aroma calibration is the Le Nez du Café (The Nose of Coffee) kit — a set of 36 small bottles, each containing a single aromatic compound representative of a coffee aroma descriptor (e.g., caramel, dark chocolate, green pepper, jasmine). Each bottle is a type of aroma cup used to train sensory memory before evaluating actual coffees.

Kit type	Producer	Descriptors
Le Nez du Café (36 aromas)	Jean Lenoir	36 reference aromas from the coffee flavour spectrum
SCA Sensory Kit	Various producers	Aligned to WCR Sensory Lexicon descriptors
Coffee Taster's Flavour Wheel references	SCA / WCR	Anchored to defined AGTRON standards

Cup Design for Aroma Appreciation¶

In consumer and café contexts, some cups are marketed as "aroma cups" based on their design features:

Tulip-shaped cups — narrowed rim concentrates aromatics and directs them toward the nose
Lidded cups — a lid traps volatile aromatics; removing the lid releases a concentrated burst of aroma
Handleless cups — warming the hands on the cup body raises the temperature of the liquid, encouraging aroma release
Small volume — smaller cups preserve temperature and concentration; less dilution of aromatics

In contrast, wide, flat cups (demitasse variants) allow aromatics to dissipate rapidly.

Key Facts¶

Aroma accounts for the majority of perceived coffee flavour — detected via retronasal olfaction, not taste receptors
Coffee contains over 1,000 volatile aromatic compounds; the SCA Flavour Wheel organises these into hierarchical clusters
In SCA cupping, aroma is formally evaluated twice: dry fragrance (before water) and wet aroma (immediately after water addition)
Le Nez du Café is a 36-bottle professional aroma reference kit used for sensory training and vocabulary calibration
Consumer "aroma cups" are typically tulip-shaped or lidded designs that concentrate aromatics at the nose
Aroma evaluation is conducted before tasting in professional protocols because aromatic perception can be influenced by taste experience
